CONTINUOUSLY VARIABLE TRANSMISSION

摘要

The present invention relates to a continuously variable transmission with which a continuously variable gear shifting operation may be conducted freely in a constant-mesh state, no shifting shock may be generated during a low-to-high gear shift or vice versa, and torque reduction during a gear shift may be prevented. The present invention comprises a casing with which an input shaft and an output shaft are coupled; a carrier coupled with the input shaft and the output shaft; a low-speed output part comprising a first planet gear coupled with a sun gear coupled with the input shaft, a carrier coupled with the first planet gear, and a one-way clutch connecting the carrier with the output shaft so that deceleration by the first and 1-1 planet gears is generated to slow down the rpm of the output shaft; and a high-speed output part where the rpm of the output shaft is increased by means of the rotation of a second planet gear coupled with the carrier and the rotation and acceleration of a second sun gear.
